Conditions at Seal Beach in July
July: Small, Warm, and Windblown
July is the classic Southern California summer pattern. Average swell drops to 2-3ft (0.8m), yet the period remains long at 13.8s, meaning there's still some organized southern hemi energy in the water. The direction mix is dominated by SW at 45.0%, SSW at 28.5%, and WSW at 22.6%, all good swell directions for the spot. But the 2-3ft (0.5-1m) class accounts for close to 85% of the wave rose, and wave heights above 5ft (1.5m) are virtually nonexistent. Ideal wind remains at 1%, with the SW/WSW/SSW sea breeze regime firmly locked in: SW 30.9%, WSW 23.3%, SSW 20.9%. Consequently, Seal Beach turns into a windblown, textured small-wave zone for most of the day. There are still rideable shoulders on a longboard if you pick a glassy morning and a higher tide, but compared to winter the quality gap is massive. Water temp reaches 18.1°C, air average 20.0°C, and dry weather rules.
